In communications and information processing, code is a system of rules to convert information—such as a letter, word, sound, image, or gesture—into another form, sometimes shortened or secret, for communication through a communication channel or storage in a storage medium. An early example is an invention of language, which enabled a person, through speech, to communicate what they thought, saw, heard, or felt to others. But speech limits the range of communication
Base32 is the base-32 numeral system. It uses a set of 32 digits, each of which can be represented by 5 bits (25). One way to represent Base32 numbers in a human-readable way is by using a standard 32-character set, such as the twenty-two upper-case letters A–V and the digits 0-9. However, many other variations are used in different contexts. This is an
Amazonas ( (listen)) is a state of Brazil, located in the North Region in the northwestern corner of the country. It is the largest Brazilian state by area and the 9th largest country subdivision in the world, and the largest in South America, being greater than the areas of Uruguay, Paraguay, and Chile combined. Mostly located in the Southern Hemisphere, it is the third largest country subdivision in the Southern
An alphanumeric grid (also known as atlas grid) is a simple coordinate system on a grid in which each cell is identified by a combination of a letter and a number. An advantage over numeric coordinates such as easting and northing, which use two numbers instead of a number and a letter to refer to a grid cell, is that there can be
The World Geodetic System (WGS) is a standard for use in cartography, geodesy, and satellite navigation including GPS. This standard includes the definition of the coordinate system’s fundamental and derived constants, the normal gravity Earth Gravitational Model (EGM), a description of the associated World Magnetic Model (WMM), and a current list of local datum transformations. The latest revision is WGS 84 (also known as WGS 1984, EPSG:4326), established and maintained by the United
UN M49 or the Standard Country or Area Codes for Statistical Use (Series M, No. 49) is a standard for area codes used by the United Nations for statistical purposes, developed and maintained by the United Nations Statistics Division. Each area code is a 3-digit number which can refer to a wide variety of geographical, political, or economic regions, like a continent, a country, or
In software engineering, a class diagram in the Unified Modeling Language (UML) is a type of static structure diagram that describes the structure of a system by showing the system’s classes, their attributes, operations (or methods), and the relationships among objects. The class diagram is the main building block of object-oriented modeling. It is used for general conceptual modeling of the structure of the application,
Toponymy , toponymics, or toponomastics (from Ancient Greek: τόπος / tópos, ‘place’, and ὄνομα / onoma, ‘name’) is the study of toponyms (proper names of places, also known as place name or geographic name), their origins and meanings, use and typology. Toponym is the general term for a proper name of any geographical feature, and full scope of the term also includes proper names of all cosmographical features. In a more specific sense, the term toponymy refers to an
A postal code (also known locally in various English-speaking countries throughout the world as a postcode, post code, PIN or ZIP Code) is a series of letters or digits or both, sometimes including spaces or punctuation, included in a postal address for the purpose of sorting mail. As of February 2005, 117 of the 190 member countries of the Universal Postal Union had postal code systems. Although postal codes are usually
The Open Location Code (OLC) is a geocode system for identifying an area anywhere on the Earth. It was developed at Google’s Zürich engineering office, and released late October 2014. Location codes created by the OLC system are referred to as “plus codes“. Open Location Code is a way of encoding location into a form that is easier to use than showing
